I tried searching on this but for some reason I time out before I get any results..

Can anyone please tell me how I go about changing my freehub for Easton EA90 SL wheels? These have the R4 hubs. I need to switch from Shimano to SRAM (Easton has a freehub body for each type of spline pattern now).

Thank you in advance!

Shimano and Campagnolo have cassette lock ring tools for their hubs ,
of course they are not the same.
each has a different spline tool.

can't see a damn thing from the keyboard, take it to the bikeshop.

He doesn't want to change the cassette, he wants to change the entire freehub body.

Easton's web site has tech documents for their wheels and hubs. Look here and scroll down to the R4 area: http://www.eastoncycling.com/road/technology/downloads/wheel-service/

If that isn't enough, contact them directly.

+1 I just checked out the link, and as I thought, the R4 is very similar to my R3's. Good illustration under 'disassembly' on the site. For freehub change, it is basically just unscrewing the end piece holding the freehub in place, and removing the freehub, then reversing the process with the other freehub. Just do not forget to use the proper amount of lube for the new freehub.:)

There's a sleeve bolt, that the axle passes thru on shimano stuff, 10mm allen unscrews, the sleeve bolt holds the 2 bits together .

guess Campag may use similar mechanical connection. , it's a a form follows function kind of thing..
still general shop procedure, got to pull the cassette off the body , pull the axle ,
then you start on the separation.
